Twisted stainless steel band given out as an IPP11 souvenir by Tim Rowett. The goal is to make it into a double Mobius strip (Mobius strip with two thicknesses). In its current state the twisted band is not a Mobius strip.

Everlasting Gobstopper by Lee Krasnow. The puzzle is a sold-out, limited edition, #2 of 8. The pieces are etched with the type of wood (see pieces photo for an example).

The first two pictures are from a recent auction by Nick Baxter. The subsequent two pictures show the puzzle's current non-assembly. I've been unable to r...

"Make a symmetric, one band Celtic Braiding using all the 19 pieces." Although it looks like a jigsaw puzzle, it is much more difficult, given that the target shape is not known. This is a really nice puzzle and is rather heavy (around 1 lb or 0.5 kg, I would estimate). Comes with original instructions, no solution is provided (available upon request).

Described by Mike as the "de-luxe" version this is a clever packing problem in oak and wenge. Check out Mike's original comments at www.puzzzlevision.com

Eric has found a way to cover this problem by slightly altering the dimension of the cube. Eric’s first atte...

The letters of ELIZABETH incorporated, along with four other nondescript connecting pieces, into a solid cube with no voids.
